The Adsorption Behavior of Quizalofop-P-Ethyl in Montmorillonite and Kaolinite

摘要：

　　To clarify the fate and the potential harm of quizalofop-p-ethyl in soil environment,to provide a scientific use,and to assess its environmental safety,adsorption behavior of quizalofop-p-ethyl in montmorillonite and kaolinite had been studies with the help of batch equilibrium method,high performance liquid chromatography,the FT-IR spectroscopy technique and XRD experiment.Results showed that:①The adsorption of quizalofop-p-ethyl in two kinds of clay minerals tested basicly reached balance after 12 h.②Its adsorption isotherms in two kinds of clay minerals were well fitted by the Langmuir equation,its adsorption capacities of quizalofop-p-ethyl was found to be in order of montmorillonite> kaolinite.③quizalofop-p-ethyl could enter the interlayer of montmorillonite,but not entered the interlayer of kaolinite.The hydrogen bonds might exist between quizalofop-p-ethyl and two kinds of clay minerals.
